An outdoor LED screen is a high-brightness digital display that shows full-color images with an excellent viewing angle, even outside in the sun. It’s intended to be rain, snow, and other extreme weather resistant, perfect for outdoor use.

The most important features of an outdoor LED billboard are that they work together to provide high visual performance. These are:

• Outdoor LED Modules: SMD LEDs with weatherproof rings.
• Cabinet (optional): The cabinet that holds the LED modules, receiver card, power supplies, and cables provides stability and support.
• Power Supply: Supplies power distribution to the LED modules.
• Receiver Card: A Control interface for controlling the LED screens that receives video signals.
• Power Cables: Power supply to the LED modules is transmitted via power cables.
• Network Cables: The LED modules connect to the control system via network cables.
• LED Sender: Converts input signals into visual content for the screen.

Outdoor screens are typically more than 5000 nits in the daytime, adjustable for nighttime. Some specialized models are up to 10000 cd/m².

Outdoor LED screens can be mounted in various ways depending on location and application:

• Ground Installation: The screen is installed on the ground and is perfect for long-distance visibility, with a superb video experience.
• Embedded Installation: The screen is integrated into building facades with other steel elements, and looks slim and modern.
• Hanging Installation: Often used above store fronts, it is simple and fashionable, perfect for demanding attention.
• Pillar Installation: Suitable for open spaces or highways with no wall support, and the screen is supported on poles.
• Wall-mounted Installation: Screen is fixed to walls, making use of wall support in a bid to save space.

It has two major modes of access: front service and rear service.

• Front Service

Front service maintenance enables you to fix LED modules from the front of the screen. It’s mostly utilized for wall-mount installation.

• Rear service

Back servicing provides access at the back of the screen and is widely employed in areas where sufficient space is available behind the indoor LED panel.

You can control the outdoor LED screen in various ways to suit various needs and circumstances.

• Synchronous control

Plug a computer into the controller via HDMI or DVI, and then plug the controller into the LED screen via a network cable for real-time updating.

• Asynchronous Control

For mobile flexibility, Wi-Fi or 4G/5G of a phone or iPad can be connected to the controller, and then the controller controls the LED screen using a network cable

• Cluster Control

Supports Internet remote control in which a computer or phone is connected to a cloud platform that communicates with the controller via 4G/5G/LAN/Wi-Fi, and then controls the LED screen by means of a network cable.

The size of the outdoor LED screen may be very large or very small, depending on the installation location, even to a single module.

In general, an outdoor LED video wall can be sized in two ways: by LED modules and by cabinets.

If it is sized by LED modules, screens are built by connecting one module or hundreds of them. Those common module sizes are:

• 320×160mm
• 160×160mm
• 256×128mm
• 192×192mm
• 250×250mm
• 480×320mm
• 500×250mm

Otherwise, when near cabinets, the dimensions of an outdoor LED screen can be established by the number of cabinets that are joined together to achieve a huge display, consisting of several cabinet units.

The usual cabinet sizes are as listed below:

• 960×960mm
• 1280×960mm
• 640×640mm
• 576×576mm
• 512×512mm
• 1000×500mm
• 500×500mm
• 1000×1000mm

800×900mm

Outdoor LED screens and indoor LED screens are unique in the following ways:

1. Environment of Use:

Indoor LED screens are used in stable environments like shopping malls, conference rooms, and cinemas, where they do not have to endure rain or extreme temperature changes, so their need for ruggedness is less.

Outdoor LED panels are designed with harsh weather conditions like rain, sunlight, temperature, and dust in their considerations. They are more oriented towards stability and durability to perform better under adverse conditions.

2. Display Performance:

Indoor screens are more interested in color vividness and details with higher resolution and higher color saturation.

Outdoor screens are high brightness (5000–10000 nits) and high contrast for daylight visibility.

3. Technical Specifications:

Indoor LED displays utilize narrow pixel pitches (e.g., P0.9, P1.2, P1.5, P1.8, P2.5, P3) for extremely high definition and high details.

Outdoor LED displays use large pixel pitches (e.g., P4, P5, P6, P8, P10) for distant-view observation and cost saving.
